pneumatic renovator as is necessary to illusatented April 20, 1909,

Referring to the drawings in detail, 1 .designates the sup orting -base or' latforrn which is mountc uponsuitable roli) shown). 2 indicates the fan casing, and 3 the 'motor -for operating the same. A conduit 4 extends 'from the fan casing to a dust box 5 carried bythe platform 1. As the novel features-in this invention d not res1de 4 Ain any specific' construction of fan or motor,

these two elements are illustrated in a conventional way only, it being understood that I any type of fan' andmotor may be employed.

latform is the v 'Mounted at the end of the suction chamber, preferab y cylindrical, and provided withend plates 7,-which arev e 'tended and support'between' them shoes 8. Tlle lower edges o surface bein cleaned. The space between the lower e gesof the chamber constitutes the chamber '6 and shoes 8 lie] in the same plane, as indicated at 9, and' are adapted t'o make direct contact with the the suction mouth. If desired and as shown,t i

a rotary= brush 10 may be mounted in the suction chamber on a shaft 11, carrying at its end a suitable.y ulley`12, adapted to be driven by means. 0F the 4motor shaft.

Mounted within the upper part of the sucsupported and provided with a projecting through a narrow slot 14 formed in the wall a belt (not'shown) from ltionchamber 6`is a sliding door 13, rotatably y atl ofv the chamber 6. This door 'servestopon- 'i trol the passage of air through the main intake opening-16,' and, .when in the position shown in Fig.' 2 shuts off communication between the suction chamber and the dust box.

When, however, the. doorl is rocked tothe position shown in dotted lines, dust laden air coming up through the suction mouth ma the conduit 4 tot 1e fan. p

Projecting fromthe front wall of the dust 4boxjs an auxiliary 'intake nozzle 17, which"is `so shaped as to readily accommodatethe end 952'.' pass through the o ening 16, and on throng usually carries at its other end a 4suitable cleaning tool or suction nozzle designed to be moved over thesurface to be cleaned;v Asvinvention,A they are not illustrated, a though the-auxiliary intake 17 designed to lreceive hose, and which is a feature of the pres-'- '100. 'of a suitable piece of exible hose which hose i rent invention, `is clearly shown in the drawing. A removable cap 18 serves to close this auxiliary intake when not' in use. Ext-end- `ing'aer'oss the mouth of the conduit 4, where .1t enters the dust box 5, is a wire or other foraminous screen 19, and in the bottom of the dust box immediately below this screen,

,lis placed a removable drawer20.

l is therefore evident that., by properly'manipulating the door 13 and the cap 1S, air maybe drawn `into the apparatus through either the main or auxiliary intakes, and then, in either case,

vthe sii' will be compelled to pass through the screen 19, which screen will'intercept the larger particles oflust and cause them to be .de osited in the drawer 20.

TVlien the machine is used to clean lloors by movin the suction mouth 'back and forth I )over the oor, the valve 13 is brouglit to a 2Q position to vuncover the opening 16, and the placed over the auxiliary intake 17, in whic i case the entire pull or suction vaction lof. the lan (is through the suction .inmitlnwhich is in contact with the floor. When, however, the llexible hose with the 5 suction 'nozzle at its end is used to do the cleaning, `the machine remains stationary,

- intake,A the cap 418, having lirst been removed. Now in order to obtain the full sucand the said hose is coupled to the auxiliary A of the fan whether. the suction ihouih is being basesuction producing means carrie used, oi'wliet.lier the llexible hose and suetion nozzle are employed, and at the same time l have provided a simple form of apparatus whereby both the suction mouth and suction nozzle can be employed with full force and elIeet in one and the same machine.

lt will thus be seen that l have provided a 'simple and eilicient'means for controlling the passageof dust laden air through a plurality of intakes, and for intercepting the larger particles of dust delivered'from eitheiiintake, and it is' thoughtl th'at the numerous advan tages of in v invention will be readily appreciated by those skilled in the art;

What I claim is:- 's' 1. ln a pneumatic renovator, a sup )ortiiig d thereby, a suction chamber having a suction mouth, also carried by said base and conimunicating with said Vsuction roducing 1neans',an auxiliary intake nozz e having By employconununication with the suction producin means', and a slid-able door mounted in sai( suction chamber for shutting oii the coinmunication between the latter and the snction producing means.

2. In a pneumatic renovator, a supporting base, suction producing means carried by said base, a chamber also carried by said base, and having a suction mouth adapted to make contact with the surface beingcleaned a dustbox having communication with said chamber,an intake nozzle projecting from the dust-hex, a conduit connecting said dustbox and suction producing means, a l'oraminous screen extending across said conduit, and means between said"screen and suction mouth for controlling the passage ol` air through said chamber.

3. In a pneumatic ieiiovator, asupporting base, a dust-box having an intake, a chamber provided with a suction mouth, saidchainbei communicating by an opening with the dust-v box, a suction creating means, a conduit connecting said dust-box and suction creating means, a loraminoiis'screen extending across said conduit,'and separate means for controlling at Will\the passage of air through said intake and opening.l I

4. In a pneumatic renovator, a supportin base, a dust box and suction chamber carrie by said base, said suction chamber bein provided With a suction mouth and wit an opening communicating with said dust box and said dust-box having an intake nozzle projecting from a wall thereof, a sliding door `for controlling said opening, mounted within said chamber, and meansprojecting through a'wall of the chamber for operating said sliding door. n l

5. In a pneumatic renovator, a supporting base, a dust box carried thereby, a suction chamber having a suction mouthand a main intake opening communicating with said dust box, an auxiliary' intake nozzle projecting from the dust box, and separate means 'for closin the main andthe auxiliary intake, as desiredi c 6. In al pneumatic renovator, a su porting base carryiiiga dust b ox, fan, an suction chamber having a suction mouth, said chamber and box communicating with each other by a main intake opening, means for closing said main intake opening, an auxiliary intake nozzle coiiimunieetin lwith said box', a coriduit connecting said ox and fan, a. foraminous screen disposed across the mouth of said the said nozzle. In testimony whereof I ave aixed my signature in-pres'ence of two. witnesses.
